Mesacol Mesalazine [5-aminosalicylic acid] Azathioprine
ModerateTaking mesalazine together with azathioprine may raise the risk of kidney problems, as both can harm the kidneys, and the same is true of NSAIDs.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
